A SPoC can assign User charts through the Users tab on the Chart record. This way, you can generate a handful of charts on a new hire's dashboard without the need to impersonate each User.
Note: You can't add multi-series charts through the Users tab. A SPoC can impersonate the User to add a multi-series chart to the dashboard.
Go to System Setup > Charts.
Click the chart you want to assign.
Click the Users tab.
Click New User Chart.
Select a User from the drop-down list.
Select a Chart Type from the drop-down list.
Assign a number in the Position field to set the chart's position on the User's dashboard.
Note: Users can drag and drop charts on their dashboard to rearrange them in any order they want. This automatically updates the Position field.
